ABSTRACT:
A prosthetic joint implant for replacing a portion of a bone having a base member 10 with a first surface 11 for positioning toward a surface of the bone. The first surface 11 includes a shallow recessed portion 13 and a raised peripheral rim 14 at an outer edge 15 of the recessed portion. The joint implant 1 further includes a separate augment member 40 having a first face 41 adapted to be selectively positioned against the first surface 11 of base member 10. The first face 41 includes a peripheral outer edge 43 thereabout and an elongated raised rib 44 having an outer shoulder 45 which abuts an inner shoulder 16 of raised rim 14 of base member 10. The raised rib 44 of augment member 40 extends only about halfway or less around the peripheral outer edge 43 of augment member 40. The raised rib 44 provides resistance to shear forces that act toward the direction of the rib 44 positioned along an outer side of the base member 10 when the augment member is connected thereto.
